TRENTON — A New Jersey Democrat leading the investigation into traffic jams orchestrated by Gov. Chris Christie's aides says his committee will look into a new allegation of political retribution by the Republican administration.

Appearing on NBC's "Meet the Press" on Sunday, Assemblyman John Wisniewski says Hoboken Mayor Dawn Zimmer's allegation that Superstorm Sandy recovery funds were withheld from her town because she wouldn't support a politically connected real estate development is a serious new charge.
